MOP-W SPEGIFICATION formingpart of Letters Patent No. 736,065, datedAugust 11, 1903. Application led December 13, 1902. Serial No. 135,108.(No model.)

To all whom t 1v1/ty concern:

Beit known that I, ARTHUR M. BURNHAM, a resident of Gardiner, in thecounty of Kennebec and State of Maine, have invented certain new anduseful Improvements in Mop- VVrin gers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it 'appertains tomake and use the same.

My invention relates to an improvement in mop-wringers, the object ofthe invention being to provide improvements of this character which willgreatly facilitate the wringing of a mop by power applied to afoot-treadle and wring the water from the mop into a pail or receptaclecarrying the treadle and other wringing mechanism, an d, further, toprovide an improved spring-treadle, an improved spring mop-guide, andimproved combinations of parts, as will hereinafter appear. Y

With these objects in view the invention -Y consists in certain novelfeatures of construction and combinations and arrangements Vof parts, aswill be more fully hereinafter ,described, and pointed out in theclaims.

In the accompanying drawings, Figure lis a view in elevation,illustrating my improvements. Fig. 2 is a view in section, and Fig. 3 isa top plan view.

I represents arectangular pail or receptacle having` revolnbly supportedat its upper edge at one end a preferably concave stationary roll 2 andbetween which and a movable roll 3 the mop is wrung, as will be morefully hereinafter described.

To the sides of the pail l bars 4 are secured and are bent into thecompound curve shown and project beyond the forward end of the pail,forming feet to prevent upsetting in applyin g pressure in wringing themop. To these bars 4 a swinging frame 5 is pivotally connected by screwsor bolts 6 and comprises a bar of metal bent at two points between itsends, providing a straight bar?, extending over the pail and carryingthe roller 3, and the ends of said bar are slightly curved edgewise andpivoted to bars 4, as above explained. This frame 5 is normally held inits inoperative position against the top of pail l at one end by aspring S, which comprises a springn n Y l wire coiled between its ends,as shown, and

having one end bent around and secured to a rivet 9 on bar 4 and thenbent at right angles, forming a lug IO,`projecting over the upper edgeof bar 4 to prevent pivotal movement on rivet 9. The other end of thespring extends upward and is connected by a wire link 1l with frame 5,the link being preferably removably connected to the frame.

The bars 4 have secured thereto, by means of bolts 12 or otherwise,sleeves 13 to pivotally support my improved treadle 13, which lattercomprises a piece of heavy spring-wire, bent at two points between itsends, forming the treadle or foot portion 14, and the ends of thetreadle are coiled, as shown at 4l5, and supported on sleeves 13, andthe extreme ends of the treadle are bent, forming hooks 16 to engage theframe 5 near the pivotal point thereof.

A mop-guide. 17 is provided in the pail and comprises a wire bent at twopoints between its ends, as shown at IS, to receive retaining pins orbolts I9. The ends of the wire t en extend upward to near the bottom ofrol 2 and then bend at right angles and extend parallel and are bentinto the wavy orirregular shape shown and then bulge ontwarddao/-thesides of the pail and are secured thereto by screws or bolts, forming aguide to direct the mop to the center of roll 2 and in position to bemost effectually squeezed between the rolls 2 and 3.

A lifting-bail 2O is pivotally supported at its ends in the sides ofpail l, and a stop or shoulder 2l is secured to the side of thepail toprevent the bail from swinging over against the movable frame 5, whereit might interfere lwith the perfect operation of the wringer.

The operation of my improvements is as follows: When a mop is to bewrung, it is placed in the pail or receptacle I and directed by guide I7to the center of roll 2. The operator then presses down on treadle 13 toswing roller 3 over against the mop and press it between the rolls toeffectually wring the water from the mop wh en it is drawn from betweenthe rolls. As the hooked. ends of treadle engage swinging frame 5, nearthe pivotal support of the frame, it will move frame 5 a considerabledistance vwith comparatively slight movement of the treadle, and as theframe moves toward the roll 2 hooks 1G will move away from the pivots 6,and a greater leverage is exerted by the treadle to effectually squeezethe mop.

By constructing the treadle 13 and guide 17 both of spring-wire andshaping and mounting the guide as above explained they will yield tocompensate for tangles or bunches of the mop and not injure the wrnger.The form ofr spring 8 and its connecting-link ll are also improvementsover anything of this character heretofore known.

A great many changes might be made in the general form and arrangementof parts described without departing from my invention,

`and hence I do not conne myself to the precise construction set forth,but consider myself at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a mop-wringer, the combination with a stationary roll, of apivoted frame, a roll carried by the piroted frame, a treadle connectedwith said pivoted frame, a spring and a link pivoted at one end to saidspring and connected at its other end to the pivoted frame independentlyof the treadle and operating to move the frame away from the stationaryroll.

2. In a mop-wringer, the combination with a pail or receptacle, of astationary roll at one end of the pail, a frame pivoted to the pail andcarrying a roll, a treadle composed of heavy spring-wire, coiled at itspivotal points between its ends,'and having its ends bent to engage theframe and swing it, when the treadle is depressed.

3. In a mop-wringer, the combination with a receptacle, of a stationaryroll at one end thereof, a movable frame carrying a roll, a springnormally holding the frame away from the stationary roll, aspring-treadle to move the frame to bring the rolls together and aspring mop-guide attached at one end to the receptacle below its top andat the other end to the sides of the receptacle near its top toyieldingly guide the mop between the rolls.

4. In a mopwvringer, the combination with a pail or receptacle, a rollerjournaled therein, a swinging frame pivoted to the sides of the pail,carrying a roller and bent edgewise, or curved at their ends, and atreadle having a sliding connection with the curved or bent ends tooperate the frame.

5. In a mop-wringer, the combination with a pail or receptacle, a rollerjournaled therein, a swinging frame pivoted to the sides of the pail,carrying a roller, and bent or curved edgewise at their ends, a treadlepvoted to the pail between its ends, and the ends of the treadleengaging` the curved or bent ends of the frame near its pivotal pointand which move away from the pivotal point as the frame is swung tobring the rollers together.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
